WLAN Having Load Balancing by Access Point Admission/Termination

1. An access point, comprising: a module for determining a loading level of the access point; and an association module for determining whether to terminate an association with a mobile station based at least in part upon the loading level of the access point, wherein the association module is further adapted to terminate an association with a particular mobile station based on the number of access points the particular mobile station can associate with.

2. The access point according to claim 1 , wherein the access point forms a part of an 802.11 network.

3. The access point of claim 1 further comprising: a memory for storing mobile station and access point association information.

4. The access point of claim 3 wherein the association module is further adapted to determine whether to terminate an association with the particular mobile station based on the stored mobile station and access point association information.

5. The access point of claim 1 wherein the module for determining a loading level of the access point is adapted to determine a number of mobile stations associated with the access point.

6. The access point of claim 5 wherein the module for determining a loading level of the access point is further adapted to determine a bandwidth usage of the mobile stations associated with the access point.

7. The access point of claim 1 wherein the module for determining a loading level of the access point is adapted to determine a transmission queue length.

8. The access point of claim 1 wherein the module for determining a loading level of the access point is adapted to determine a number of transmitted error packets.

9. A method of distributing access point loading in a wireless network, comprising: determining a loading level of an access point; determining whether to terminate an association with a mobile station based on the determined loading level of the access point; and terminating an association with a particular mobile station based on the number of access points the particular mobile station can associate with.

10. The method of claim 9 wherein determining a loading level of an access point comprises: determining a number of mobile stations associated with the access point.

11. The method of claim 9 wherein determining a loading level of an access point comprises: determining a transmission queue length.

12. The method of claim 9 wherein determining a loading level of an access point comprises: determining a number of transmitted error packets.

13. The method of claim 9 wherein determining a loading level of an access point comprises: determining a bandwidth usage of mobile stations associated with the access point.

14. The method of claim 9 wherein determining a loading level of an access point comprises: determining a quality of a link between the mobile station and the access point.

15. The method of claim 9 further comprising: transmitting an association response to the mobile station.

16. The method of claim 15 further comprising: determining the association response, wherein the association response includes data rates supported by the access point and the determined loading level.

17. The method of claim 9 further comprising: determining the access point should not accept associations with mobile stations, the determination based on the determined loading level of the access point.

18. The method of claim 9 further comprising: terminating an association with the mobile station based on the determined loading level of the access point.
